Paul Lambert is suing Norwich City for up to £2m, according to the club's chairman. Alan Bowkett told a fans' forum at Carrow Road that Lambert, now manager of Aston Villa, was suing for alleged breach of contract.

The BBC reported that Lambert was seeking between £1.5m and £2m following his bitter move away from the club this summer. Neither Aston Villa nor Paul Lambert have commented.

The Norwich chairman said he was disappointed with the way Lambert left the club, taking over at Villa on 2 June. Lambert, who has said he had reasons for leaving that he wanted to keep private, spent three years at Norwich and guided the Canaries to back-to-back promotions from League One before finishing 12th in Premier League.
